Most Helpful Positive Review 500 barrel
Barrel is great service so so. Took 6 weeks to get it. Was in stock at time of oeder. They said it was out. 4 emails and 3 calls. No returned msg or calls. I realize that there is covid 19 but 6 weeks no return email or call?
Most Helpful Negative Review Mossberg security barrel (matte black)
After receiving and unpacking. Barrel looked used. Scratches and rub marks over it where bare metal was showing. Very dissapointed I waited one whole year for it to arrive. How this item ever got past quality control is beyond me.

Mossberg Barrel

by Red, Verified Owner from MN, United States Written on April 10, 2025
I ordered this barrel for a replacement for my mod 500 with a 20-inch heavy barrel. The picture on the web site showed a barrel with the attachment that goes over the magazine tube. This is the type of barrel I now have. The barrel I received has the screw type attachment that screws into the magazine tube. I cannot use this barrel. The picture should be changed. Disappointed.
Pros:
  • None
Cons:
  • does not fit

As an avid shotgun enthusiast, I recently acquired the Mossberg 500 12 Gauge Security Barrel with an 18.5-inch matte finish, and I must say, I'm thoroughly impressed.

First and foremost, Mossberg's reputation for reliability is well-deserved, and this barrel is no exception.

The 18.5-inch length strikes a perfect balance between maneuverability and accuracy, making it suitable for various scenarios.

The matte finish not only gives the barrel a sleek and tactical appearance but also helps reduce glare, ensuring better visibility in low-light conditions. Additionally, the matte coating provides an extra layer of protection against scratches and corrosion, enhancing the barrel's durability and longevity.

Installation was a breeze, thanks to Mossberg's user-friendly design and precision engineering. The barrel fits snugly onto the Mossberg 500 receiver, with no wobbling or play, ensuring consistent and reliable performance shot after shot.

In terms of performance, I found the Mossberg 500 12 Gauge Security Barrel to be exceptionally accurate, even at extended ranges. Whether firing slugs or buckshot, I consistently achieved tight groupings, reaffirming my confidence in this barrel's capabilities.

Overall, the Mossberg 500 12 Gauge Security Barrel with an 18.5-inch matte finish is a top-notch choice for anyone in need of a reliable and sturdy shotgun ba...

short barrel

by Jim, from NJ, United States Written on September 1, 2020

Pros:
  • short but still legal in my State
Cons:
  • None
Best Used for:
  • Home Defense
